Description of the Invention: [Technical Field] The present invention relates to a power saving device, and more particularly to a power saving device suitable for a wireless mouse. 5 [Prior Art] The general wireless mouse uses the internal battery to provide the power required for its operation. Because the battery power is extremely limited, the wireless mouse has the power saving mode to provide more savings. The effect of electricity. As shown in Figure 1, when the 10-wire mouse does not move for a period of time, the microprocessor 90 will go to sleep and turn off most of the power to bring the wireless mouse into power save mode. Thereafter, in order to determine whether the wireless mouse is moved again, the microprocessor 90 in the wireless mouse is intermittently woken up to drive the light-emitting diode 92 (LED) of the light-emitting unit 91 to emit a light source, and the light source is reflected in the light-sensing On the unit, the light 15 sensing unit 93 converts the optical signal into an electronic signal as a basis for judging whether the mouse φ is moved. If there is movement, the wireless mouse is woken up; otherwise, the power saving mode is still entered. Although the method can reduce the loss of power supply, the intermittent wake-up action does not really enter the power-saving mode. In addition, as in the Republic of China Patent Notice No. 562326, "Power-saving mechanism for the use of 20 products for radios", After the wireless mouse has not been used for a period of time, it causes the vibration sensor inside the wireless mouse to be short-circuited by shaking, causing it to generate a trigger signal to wake up the wireless mouse, thereby improving the power loss of the intermittent gas measurement. All power-consuming power supplies can be turned off, leaving only a small amount of power. However, as shown in Figure 2, when the wireless mouse is idle, the position where the mercury of the 5 1287736 motion sensor (mercury switch) stops is not determined, and it may stop at position A, causing the vibration sensor to open. The wireless mouse does not consume power when it enters the power saving mode, but it may also stop at position B, causing the vibration sensor to be short-circuited and causing the wireless mouse to consume power when it enters the power saving mode, resulting in a lower power saving mode than in use. More power consumption. Therefore, since the vibration sensing is not able to ensure an open state at all times, when the wireless mouse is not used for a period of time, the wireless mouse enters a power saving mode, and the vibration sensor is exactly one. In the short-circuit state, the power supply will be lost through this short-circuit loop. At this time, the wireless mouse cannot achieve the purpose of power saving. 〇 It can be seen that the power-saving design of the conventional wireless mouse still has many defects and needs to be improved. SUMMARY OF THE INVENTION The main object of the present invention is to provide a wireless mouse power saving device 15 so that the wireless mouse can not enter the power saving mode after being used for a period of time without the need to test the wireless Whether the mouse moves, thereby achieving the goal of saving maximum power consumption. Another object of the present invention is to provide a wireless mouse power saving device that ensures that the wireless mouse's power saving device can operate effectively. According to the feature of the present invention, a power saving device for a wireless mouse is proposed. Hai Wireless 'moon milk has a microprocessor, the microprocessor has a wake-up day Γ Γ no m can enter people - power saving mode to save power consumption, when the wake-up pin is triggered by the mine M j processing The wireless mouse will be awakened by the province, the power saving device includes: - an elastic conductor unit, 20 1287736 = ^ the microprocessor wakes up; and - the contact conductor unit, the body ΓΤ, and the contact conductor The phase separation of the unit, the early 70 series is separated from the contact conductor unit by an appropriate distance, so that the conductor unit can be in contact with the contact conductor unit when subjected to vibration, and the elastic conductor unit can be used with the moving wire mouse. The contact conductor is in early contact to trigger the wake-up chat with the predetermined potential. [Embodiment] The present invention relates to a power saving device for a wireless mouse. First, FIG. 3 is a schematic diagram of a first embodiment of the present invention. In Fig. 3, the wireless mouse set is provided with a microprocessor i and a power saving device 2. The microprocessor 1 has a wake-up pin 11, and the power saving device 2 has a contact conductor unit 21 and a resilient, conductive conductor unit 22. The elastic conductor unit 22 is coupled to the wake-up pin 11 of the microprocessor. The contact conductor unit 21 is coupled to a pre-set potential such as a ground potential, and the elastic conductor unit 22 is separated from the contact conductor unit 21 in a normal state. The elastic conductor unit 22 is spaced apart from the contact conductor unit 21 by a distance d which is in contact with the contact conductor unit 21 when the elastic conductor unit 22 is subjected to vibration. In the present embodiment, the contact conductor unit 21 is a metal needle body, and the elastic conductor unit 22 is a spring element wound around the contact conductor unit 21. In this embodiment, when the wireless mouse is idle for a period of time, it enters a power saving mode to save power consumption. When the user moves the wireless mouse again, the elastic conductor unit 22 of the power saving device 2 of the wireless mouse is shaken left and right by the force and is in contact with the contact conductor element 21, and is coupled to the unit 21 through the contact conductor 7 1287736. The preset potential triggers the microprocessor to wake up the pin, and wakes the wireless mouse in the power saving mode. In addition, please refer to FIG. 4 again, which is a schematic diagram of a second embodiment of the present invention. The present embodiment is identical to the previous embodiment in that the difference is in the configuration of the elastic guide body unit 24. In the present embodiment, the elastic conductor Cuiyuan is a spring piece provided with a weight element 241, and the elastic conductor unit 24 is disposed beside the contact conductor unit 23 and spaced apart from the contact conductor unit when the elastic conductor unit 24 is subjected to vibration. The elastic conductor unit 24 is coupled to the wake-up pin 11 of the microprocessor 1 at a distance d between the 23 contacts. The contact conductor unit 23 is coupled to a predetermined potential of, for example, 10 ground potential. Therefore, when the mouse enters the power saving mode, when the user moves the wireless mouse again, the elastic conductor unit 24 will be shaken left and right due to the force and contact with the contact conductor unit 23, and the micro-processing is triggered by the preset potential. The wake-up pin n of the device 1 wakes up the wireless mouse in the power saving mode. 15 By the first and second embodiments of the present invention, a power saving device for a wireless slider can be provided, which enables the wireless mouse to be used in a power saving mode after being used for a period of time without intermittent use. Test whether the wireless mouse is moving, thus saving the maximum power consumption. In addition, since the contact conductor unit is separated from the elastic conductor unit in the normal state, it is possible to ensure that the power-saving device of the wireless battery can operate effectively. In the first and second embodiments of the present invention, for the sake of simplicity, the preset potentials are all described by the ground potential (GND). Therefore, the wake-up pins of the microprocessor are preset to a high voltage. Of course, an external pull-high resistor can be added to ensure that the voltage level of the wake-up pin 8 1287736 is kept at a high voltage. Similarly, the 'preset potential can also be set to a system positive (VCC), therefore, the microprocessor's wake-up pin must be set to a low-voltage internal, of course, can also be externally added to the grounding resistance (puii such as (10) _ ), to maintain the voltage level of the wake-up pin at ground (4). The wake-up pin of the micro-processing number 5 is triggered by the positive power, which is undoubtedly understood by those who are familiar with the technology. The above embodiments are merely exemplified for convenience of explanation, and the present invention is based on the above-mentioned embodiments. Limit 10 15
